Cassette type radiographic image solid-state detector

Abstract

A cassette type radiographic image solid-state detector includes: a detector unit having a scintillator for converting incident radiation into light and a detection section which receives and converts the light converted by the scintillator into electric signals; and a housing containing the detector unit, the housing having a rectangular tubular housing body which has openings at both ends and is formed in a rectangular tube shape using carbon fiber, and a first cover member and a second cover member for covering the openings of the rectangular tubular housing body, wherein a wall of the rectangular tubular housing body facing to a direction perpendicular to an incident direction of radiation is thicker than a wall of the rectangular tubular housing body facing to the incident direction of radiation.

1. A cassette type radiographic image solid-state detector comprising:
 a detector unit including a scintillator for converting incident radiation into light and a detection section which receives and converts the light converted by the scintillator into electric signals; and 
 a housing containing the detector unit, the housing including a rectangular tubular housing body formed of carbon fiber and having openings on both ends, and a first cover member and a second cover member for covering the openings of the rectangular tubular housing body, 
 wherein a wall of the rectangular tubular housing body facing to a direction perpendicular to an incident direction of radiation is thicker than a wall of the rectangular tubular housing body facing to the incident direction of radiation. 
 
     
     
       2. The cassette type radiographic image solid-state detector described in  claim 1 ,
 wherein the rectangular tubular housing body is formed by laminating members in each of which comprises fibers of carbon in which epoxy resin is impregnated. 
 
     
     
       3. The cassette type radiographic image solid-state detector described in  claim 2 ,
 wherein a number of the laminated members of the wall facing to the direction perpendicular to the incident direction of radiation of the rectangular tubular housing body is larger than a number of the laminated members of the wall facing to the incident direction of radiation of the rectangular tubular housing body. 
 
     
     
       4. The cassette type radiographic image solid-state detector described in  claim 2 ,
 wherein bundles of carbon fiber are weaved in an orthogonal direction in at least one of the laminated members 
 
     
     
       5. The cassette type radiographic image solid-state detector described in  claim 2 ,
 wherein a number of the laminated members of the wall of the rectangular tubular housing body facing to the incident direction of radiation is smaller than a number of the laminated members of a wall of an opposite side to the wall facing to the incident direction of radiation of the rectangular tubular housing body. 
 
     
     
       6. The cassette type radiographic image solid-state detector described in  claim 2 ,
 wherein the laminated members are prepregs. 
 
     
     
       7. The cassette type radiographic image solid-state detector described in  claim 2 ,
 wherein at least one of the laminated members of the wall facing to the direction perpendicular to the incident direction of radiation of the rectangular tubular housing body is thicker than each of the laminated members of the wall facing to the incident direction of radiation of the rectangular tubular housing body. 
 
     
     
       8. The cassette type radiographic image solid-state detector described in  claim 1 ,
 wherein the wall facing to the incident direction of radiation of the rectangular tubular housing body is thinner than a wall of an opposite side to the wall facing to the incident direction of radiation of the rectangular tubular housing body. 
 
     
     
       9. The cassette type radiographic image solid-state detector described in  claim 1 ,
 wherein the carbon fiber is pitch-based carbon fiber. 
 
     
     
       10. The cassette type radiographic image solid-state detector described in  claim 1 ,
 wherein a direction of the carbon fiber of the wall facing to the incident direction of radiation of the rectangular tubular housing body crosses a direction of the carbon fiber of a wall of an opposite side to the wall facing to the incident direction of radiation of the rectangular tubular housing body, by viewing in the incident direction.
